Window frost (also called fern frost or ice flowers) forms when a glass pane is exposed to very cold air on the outside and warmer, moderately moist air on the inside. If the pane is a bad insulator (for example, if it is a single-pane window), water vapour condenses on the glass, forming frost patterns.
Types of frost flowers include needle ice, frost pillars, or frost columns, extruded from pores in the soil, and ice ribbons, rabbit frost, or rabbit ice, extruded from linear fissures in plant stems. [1] The term "ice flower" is also used as synonym for ice ribbons, but it may be used to describe the unrelated phenomenon of window frost as well.
Mock cream or buttercream is a simple buttercream made by creaming together butter and powdered sugar to the desired consistency and lightness. Some or all of the butter can be replaced with margarine, or shortening. [1] [2] A small amount of milk or cream is added to adjust the texture. Usually twice as much sugar as butter by weight is used.
[6] [13] Frost flowers have a high concentration, typically 2 to 3 times greater, of bromide ions than found in seawater which is proportional to the salinity in the frost flowers. If the temperature were low enough for the sodium chloride that is present in the brine or frost flowers to freeze out, then the bromide may become readily available ...
The Catawbans is a series of three books by Gary Freeze on the history and genealogy of Catawba County in North Carolina.Freeze, a professor at Catawba College in Salisbury, [1] was commissioned by the county to write its official history, and his three book series is the result of over twenty years of work on the project.

Sarcodes is the monotypic genus of a north-west American flowering springtime plant in the heath family , containing the single species Sarcodes sanguinea, commonly called the snow plant or snow flower. It is a parasitic plant that derives sustenance and nutrients from mycorrhizal fungi that attach to tree roots.
Preserved rose blossoms and silk flowers. Flower preservation has existed since early history, although deliberate flower preservation is a more recent phenomenon.In the Middle East, the bones of pre-historic man were discovered with delicate wild flowers probably as a tribute to a passing loved one.
The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...
